IPhone : IOS SWIFT ALAMOFIRE JSON error when parsing Data

I have two questions:

1) How to resolve the following JSon parsing issue: I follow this tutorial to create an Alamofire/SwiftJson parsing Data. In the simulator I can see the output of my JSON file when println my user data.description. However I got error parsing /usersdata/1 and I can not resolve it.

2) How to change my tableview labels with the parsing data ? I have created my Outlet Labels, I have created a class to store the data, etc. I just don't know how to do that, please advise ( I am using a static tableViewCell)

UITableViewController:

import UIKit
import Alamofire
import SwiftyJson


class PersonalDetails: UITableViewController {

    required init(coder aDecoder: NSCoder) {
        println("init PersonalDetails")
        super.init(coder: aDecoder)
    }

    deinit {
        println("deinit PersonalDetails")
    }

    var usersData = [PersonalDetailsData]()

    @IBOutlet weak var dataUsername: UILabel!
    @IBOutlet weak var dataGender: UILabel!
    @IBOutlet weak var dataArea: UILabel!
    @IBOutlet weak var dataBirthday: UILabel!
    @IBOutlet weak var dataMobilePhone: UILabel!
    @IBOutlet weak var dataSignature: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()

        let prefs:NSUserDefaults = NSUserDefaults.standardUserDefaults()
        var username = prefs.valueForKey("USERNAME") as NSString

        Alamofire.request(.GET, "http://mywebsite/app/data/jsonpersodata.php", parameters: ["username": username]).responseJSON() { (request, response, data, error) in
            if let anError = error
            {
                // got an error in getting the data, need to handle it
                println("error calling GET on/usersdata/1")
                println(error)
            }
            else if let data: AnyObject = data
            {
                // handle the results as JSON, without a bunch of nested if
                let userdata = JSON(data)
                // now we have the results, let's just print them though a tableview would definitely be better UI:
                println("The data are: " + userdata.description)
 if let mobilephone = userdata["mobilephone"].string

                {
                    // to access a field:
                    println("The mobilephone is: " + mobilephone)

                }
                else
                {println("error parsing /usersdata/1")

                }}



            }.responseString{ (request, response, stringResponse, error) in
                println(stringResponse)
        }

    }



    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
           }

    @IBAction func logoutTapped(sender : UIButton) {

        let appDomain = NSBundle.mainBundle().bundleIdentifier
        NSUserDefaults.standardUserDefaults().removePersistentDomainForName(appDomain!)

        self.performSegueWithIdentifier("logout", sender: self)
    }


    }

My Class

import Foundation

class PersonalDetailsData: NSObject {

    var dataUsername:String?
    var dataGender:String?
    var dataArea:String?
    var dataBirthday:String?
    var dataMobilePhone:String?
    var dataSignature:String?
}
